To do this, create a file with root certificates of your domain CA in PEM format and Base-64 encoded (for example /etc/ssl/cert/itbroscert.pam) and specify the path to this file in the OpenLDAP client configuration file (/etc/ldap/nf or /etc/openldap/nf), #TLS_CACERT /etc/ssl/certs/ca-certificates.crt TLS_CACERT /etc/ssl/certs/itbroscert.pam

You can connect to the LDAP that use the SSL certificate over the protected LDAPS protocol (TCP port 636). In this case, the user credentials of ADUser1 are transferred over the network in a clear text form, which is not secure. To check the LDAP connection (TCP port 389), run the command: ldapsearch -v -x -D -w 'OU=Users,OU=London,OU=UK,DC=theitbros,DC=com' -H 'ldap://' sAMAccountName= ADUser1 The AD username that is used to connect to the LDAP: TestLDAPConnUsr and its password - of all, make sure that the OpenLDAP client is installed on your system: dpkg -l | grep ldapĬheck for the LDAP account ADUser1 in the container with the DN name “OU=Users,OU=London,OU=UK,DC=theitbros,DC=com”.Īn LDAP server typically accepts incoming connections on port 389 using TCP or UDP protocols.FQDN name of the domain controller.Let’s try to use the ldapsearch utility in Linux Debian to test connectivity to an Active Directory domain controller (target LDAP server). -z - sizelimit on the data size in the search query result.-w - specify password in the command prompt when running LDAP query.

-D - use the username to connect to the server.

-x - use plain authentication, not SASL.-L (-LL, -LLL) - output format (-L – LDIFv1, -LL – disable comments display, -LLL - disable LDIF version display).-A - display attributes only, without values.-n - display actions that will be performed, but not run them.
